Application filed March 5, 1913. Serial No. 752,082.

To all 'whom t may concern.'

Be it known that I, TIMOTHY F. HOR- NUNG, a citizen of the United States, residing at Sacramento, in the county of Sacramento and Stateof California, have invented certain new and useful Improvements in Tater-Supply Systems, of which the following is a specification.

The present invention relates to a means; for maintaining constant the Yhead pressure at the discharge outlets of water distribution systems, and `is particularly designed to be employed in connection with irrigation systems generally, where measured quantities of water are sold, and has for its principal object to insure the `purchaser -the required pressure or head of water purchased, and to prevent the purchaser from obtaining a greater pressure or head of water than that paid for, and vat the same time providing against theloss of water which otherwise would run to waste by an overflow thereof on the outlet therefor being closed.

Another and important object is to V.provide a means capable of performing the above objects, which is simple in construction and thoroughly eflicient in all of its operations.

Vith the above mentioned and -other -objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawing, fand pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details -of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference should be had to the accompanying drawing forming a part of this speci-- cation and wherein- Figure 1 is a top plan view of my `'improved device connected Vto the main -.distributing canal of an irrigation system, disclosing the dam across the canal, the -w-ater pressure accumulator, the overflow lreservoir situated therein, in full lines the connection between one side of the Vdam and the accumulator, and `in dotted lines the connecv tion between the overflow reservoir and the opposite side of the dam. Fig. 2 is a sectional View taken on line Q-.Q-F ig. 1 of the drawings. Fig. 3 `'is a transverse sectional view of Fig. l, disclosing `more' fully the overiow reservoir.

lVhile I 'have disclosed but one dam and distributing lateral, it is to be Yunderstood that a structure as hereinafter described is to be located alongthe distributing canal wherever it is desired to take water from vthe canal to distribute over the land to be irrigated.

Referring more particularly to the Vdrawings, wherein like vnumerals o-f reference designate corresponding parts throughout the several views, the reference numeral 1 designates a ysuitable irrigation distributing canal, .preferably constructed of concrete, and through which the water flows in the direction of the arrow-F-ig. 1, and extending across the canal at a. point where each lateral intersects therewith is a suitable removable dam or barrier 2, the upper edge of which falls short of extending to the top of the side wall-s of the canal. Communicating with the canal l immediatelyadjacent the water v.retaining side of the dam is an inlet or feed pipe 3 extending lto a suitable water accumulator 4 preferably formed of concrete and provided with a suitable discharge outlet 5 through which the water -for irrigation is discharged. within the accumulator, Vin spaced relation to vthe -walls thereof, is an overiiow reservoir 6 preferably oblong in shape, and of a size slightly smaller than .the interior of the accumulato-r 4, and said receptacle 6 is vprovided with a plurality 'of upwardly projecting, longitudinally extending, spaced `ribs or spillways 7 .connected at their lower Vends and extending to a height approximately flush with the 'highest point fof the pipe 3 Positioned and a suitable ydistance above the center of Y the outlet 5, as is necessaryito furnish .the required inches pressure of water at the discharge outlet. The upper tends of the ribs 7 are open, as at 8, -providing overflow which conveys the water which Hows into the reservoir over the edges 8 thereof back into the main canal immediately below the dani or barrier 2 thereof.

It will be observed that a portion of the water collected by the dam or barrier, will, when it attains a given height, flow through the feed pipe 3 into the accumulator 4, from where it is distributed over the land `to. be irrigated, through the discharge 5. The relative sizes of the discharge outlet 5 and the inlet 3 are such that when water is running over the dam there is more entering the inlet 3 than is capable of being distributed through the outlet 5, and consequently the height ofthe water increases in the accumulator 4 and as it reaches the tops ofthe ribs or spillways 7 overflows Athe edges 9 thereof and enters the interior of the overflow reservoir 6 from where it is conveyed by the pipe l0 back to the distributing canal below the dam or barrier 2 thereof, thus always providing a uniform height of water in the accumulator which insures a uniform discharge pressure at all times. Should the size of vthe opening 5 Vbe reduced or the opening be closed at any time, the water entering the accumulator 4 through the pipe 3 will not overflow the upper edges of the accumulatory4, but will flow over the edges 9 of the ribsor spillways 7, and: be returned to the distributing canal through the pipe l0, but there will be a sufficienty height of water in the accumulator 4 to insure the desired head pressure, should the outlet 5 be opened at any time. A suitable cut off gate ll, is mounted for closing the receiving end of the inlet pipe 3 when desired.

` Having thus described my invention what is claimed as new and is desired to be protected by Letters Patent is l. In an apparatus for the described purpose and in combination with a water distributing channel, a water pressure accumulator provided with an outlet opening for controlling the water supply to a lateral, a water supply connection between the distributing channel and the accumulator for introducing water thereinto from the distributing channel, a spillway within the accumulator and provided with an inlet opening disposed in al plane above the outlet formed in said accumulator, areturn con nection between J the spillway and the distributing channel for the discharge of the wastewater from the accumulator into the distributing channel, and an overflow bar- Vrier extending across said channel between said supply and return connections, the upper edge of said barrier terminating at a point below the upper edge of said channel and approximately evel with said spillway.

2. In an apparatus for the described purpose and in combination with a water distributing channel, a water pressure accumulator provided with an outlet opening, a

water supply connection between the dis tributing channel and the accumulator', a. plurality of spillways .within the accumulator and havingtheir inlets disposed in a plane above the outlet formed in said accumulator, a return connection common to all of said spillways extending to the distributing channel, and an overflow barrier eX- tending across said channel between said supply and return connections, the upper edge of said barrier terminating at apoint below the upper edge of said channel and approximately level with said spillways.

3. In an apparatus for the described purpose and in combination with a water distributing channel, a water pressure accumulator provided with an outlet opening, a

overflow reservoir mounted in the accumir water supply'connection between Vthe dis-1` tributing channel and the accumulator, an`

lator and provided with an overflow opening therein located in a plane above the outlet of the accumulator, a return connection between the overflow reservoir and the dis-k Jose and in combination with a .water dis-` tributing channel, a water pressure accumulator provided with an outlet opening,
